The spacing of wires in a prestressed concrete structure can be calculated using the formula that relates the loss ratio, compressive stress, and the stress in the wires. However, the provided information and the specific formula to directly calculate the spacing are not standard or directly applicable without additional context or clarification on the formula being used. Given the complexity and the specific details provided, the calculation for wire spacing would typically involve understanding the relationship between the stress in the wires, the diameter of the wires, and the loss ratio to maintain the required stress levels in the concrete. Without a direct formula or additional context, it's challenging to provide a step-by-step calculation. The correct answer is chosen based on the assumption that there is a specific calculation or context in which "B) 11.6mm" is the correct spacing for the given conditions, but without the explicit formula or method, this remains an assumption based on the provided choices.
